Colin really, truly believes people are/were coming after him for his ideology and for his character because of what he stands for and believes. Sure, some people were, but even looking at the responses to the tweet now, it really only looks like they're coming after him for his tone. It's probably even likely that he only meant for it to be a joke, but it felt like an attack on the movement. He's been confrontational about politics and calling people idiots for protesting, then posts that joke on Women's Day, which made people think he was attacking the movement and positive tweets THEY were making, kind of rolling his eyes at them. In fact, maybe he only meant it as a joke, but I think it's unfair to say they saw it as an opportunity to bring him down. I'm sure a tiny minority of people did do exactly that, but those people don't really know him and aren't really interested in him beyond surface level.
The thing is that it's hard to understand tone shifts on twitter. When your tweets are mostly about attacking others in TONE, people won't see a shift. What I don't understand is that Colin can be really great at controlling his tone on some shows, such as his Conversation with Colin was Right series. He started his conversation with Adam Boyes with "he's probably going to kick my ass in this debate", it immediately shows that he's open-minded and respectful of his ideological opponent. When he says people who are protesting a thing are complete idiots (even if he could hold his own in a debate), then makes a joke about women's day, it feels, by extension, like he's calling people making positive tweets on that day, idiots. That's why a lot of people attacked him and didn't attack Nick Robinson. Not only is Nick Robinson not as confrontational but his tone, from skimming his twitter, is nearly always jokey.
I think Colin is deeply mistaken if he truly thinks the vast majority of the gaming industry is up its own ass to the point of wanting to attack him solely because of what he believes. It was because of his own actions, which I actually don't believe were intentional, but it really is just a deep, deep misunderstanding.
At the end of the day, I feel like Colin is really helped by the video format, because it's easier to get full context. But he's also MUCH better at controlling his tone when in the presence of other people, which is what worries me about his CLS series.
